Just bought a Zeiss V8 2.8-20x56, arrived today in a tatty and box, seals broken, from Sportsman Gun Centre . As such I thought I better check it out for any defects just in case its been passed around/dropped/messed with. Noticed a strange circular line in the tube, about 30mm from the objective lens. Its faint, only caught me eye because I was taking more care than usual to inspect it.
Probably just a remnant of the manufacturing process, unless someone has tried to clean it before dispatching it and scratched it!
Any other Zeiss V8 owners with this 'feature'?
